Finding The Gradient Of A Polynomial Trendline At Different Point |
Finding The Gradient Of A Polynomial Trendline At Different Point - Excel |
|
So basically I have a progess curve for the volume of Oxygen produced over the course of an experiment and I need to find the gradient of the curve at different time points throughout a single curve. I know all about differential calculus, but I really don't have the time to work it out for every point (I have over 20 curves and 20 points on each curve) and I was wondering whether excel can work out the gradient of the trendline at specific points?
Thanks.
Thanks.

Does anyone know if there is a customer format I can use to change the percent value of a cell to basis points? I tried creating my own, but was having difficulty. For example, if the cell value in A1 is 2%, I would like to have it say 200 basis points instead.

I'm trying to write a formula that will automatically take a group of football (soccer) scores, compare them with a set of predictions, and then allocate points according to how close the predictions are to the actual scores.
E.g.
Manchester United 3 - 0 Arsenal
Prediction: 4 - 1
Points: 1
I've found a formula online that works for most scores; the correct score (e.g. 3 - 0), a correct win (e.g. 4 - 1), and in the case of a draw (e.g Man Utd 1 - 1 Arsenal, and the prediction 2 -2), correct draw (but not the correct score). The points are as follows: Correct draw (Prediction = result): 4 Correct win (Prediction = result): 3 Correct win, incorrect score (Winner correct, score not): 1 Correct draw, incorrect sco 1
The formula I found online for all but the correct draw is: =IF(A3&B3=C3&D3),3,IF(AND(A3=B3,C3=D3),1,IF(AND(A3>B3,C3>D3),1,IF(AND(A3<B3,C3<D3),1,0)))))
Could someone help me work out how I can write a formula to add before the above that will check the contents of four cells (the home score, away score, home prediction, away prediction), and if the number in all 4 cells are the same, allocate 4 points? I've tried using averages, but some combinations would void this. I've also used the SUM function, but the same happens, as with MULTIPLYING.
Something like =IF(A3:D3) are equal, 4,0
Below are a few examples of what I mean:
(Result) (Prediction) (Points)
A B C D E
3 - 3 3 - 3 4
2 - 1 3 - 1 1
1 - 0 1 - 0 3
3 - 3 2 - 2 1
Apologies in advance if I haven't explained this clearly enough.

Ok, I'm going to try and explain this. I am going to have 5 data points in cells such as A2:A6
All I need is to know if there is an upward trend or downward trend of the numbers.... I can't have something that simply takes the first and last number and checks if it's higher or lower. I need to actually see if they are trending upwards. Also how would i go about making it so that if they are trending upwards it shows an up arrow, and down arrow for downwards...
And finally, if the trend continues at the same rate, how long it will take the number to reach a goal. Each data point will be 1 week apart, with an ultimate goal needed to be achieved at the end.
This will be a completely separate formula on the sheet....
Any help?

Hello,
Firstly i haven't used excel to a great extent since my college days. So i'm having to re-learn 99.9% of everything i once new...
I am volunteering for a non profit organization and trying to create a reservation system for the rooms that they have - kind of like hotel software, but in excel (i did a similiar thing in college but for plane seats)
Please find it attached.
What i need it to do:
Copy all of the info from the main page to the guest lit (a new row each time).
From the guest list to the Gannt chart - i did a few tutorials on dynamic gantt charts using conditional formatting but cannot get them to work when based on data on a different worksheet.
Finaly is there a way to check for availabilty on any given date?
if just someone could point me in the right direction, i would be appreciate it so much words can't express!!!
Best Regards,
Jamie

I have a set of data about with approx 7500 cells all contained in one column. The data has a series of peaks that happen, and I need to identify each peak value and place it in a cell. The peak does not occur at regular intervals but they are somewhat regular, as in within 130-230 data points. So, if one could find the first peak in the first 200 cells, identify it and store it somewhere, then look in the next 200, store it, etc. I don't know how to do that in excel. Please help

Hello,
I'm pretty new at VBA and was wondering if you could help me out on this:
I have created a VBA userform but will need to have it used by at least 5 users. My question is, can it be done with all users working at the same time and when saving their work all data entered will go to one master excel sheet? if yes, would you be kind enough to share the code?
MS Access is not an option for me so I was wondering if you could help me do this in excel.
thank you so much and would really appreciate to hear from anyone soon.

I have a workbook that I have unprotected (all - workbook & worksheets). However, I have a sheet that I know is there (because I created it) but I cannot unhide. I know it is there because in the Name Manager, it points to it. Any idea how I can unhide it?
Okay, so I tried (for hours) to find a solution to this and have finally gotten frustrated to the point where i think asking here will be my best bet.
Basically I want to export data from excel worksheets to various places on a word document I had. I have created a word template as well as bookmarks for that template, as that seems to be the recommendation for performing such a task with excel.
My problem is ... Now what?
I basically have 1 constant worksheet that contains all my affiliates info (Name, Address etc), which i'd like to use to populate some bookmarks in my word template, and then i have another worksheet for the previous month, indicating sales etc for that affiliate. I intend on adding a new worksheet every month that i would use to create new invoices.
Furthermore, i'd really like to be able to update a new file (or perhaps a new page on the same file) for each company with the use of a button, similar to the one's you'd see in an access form.
Can anyone help? Let me know if you need me to clarify.
Thanks!
Matt

So I've got some data, which has the approximate form of a sine function. I want to find all the x-axis intercepts. I tried using the intercept function and swapping around the y values for the x values, but it only returns 1 value (so I'd guess it uses a linear regression to estimate a single line through the axis).
I was thinking of trying a nested if/and statement but I haven't quite figured out how to do it. Basically I want to identify the two values where it switches from positive to negative and also indentify the values where it goes negative to positive, I can then fit a straight line between them to find a better approximation of the intercept (though it might not be necessary). Preferably I'd like it all one function as I'm not doing it in VBA (I might do later though, we'll see).
Can anyone suggest how I'd find these value or the x-intercept. Any help would be greatly appreciated.

Hello,

We have a client who will pay using the 1/4, 1/2/ and 3/4 of an hour increments as follows:
From the hour mark to 6 minutes = 0 time paid
Over 7 minutes to 15 minutes = 1/4 hour 15
16 minutes to 30 minutes = 1/2 hour 30
30 minutes to 45 minutes = 3/4 hour 45
46 minutes to 60 minutes = one hour.
They work on shifts and the operation is 24 hours. Each gets 30 minutes for breaks which is not paid. Pay is biweekly and overtime is anything over 40 hours. Currently, the template we are using looks like this (sorry, I could not figure out how to paste it so you can see it in Excel layout):
WEEK 1 Sunday Monday Tuesday Wednesday Thursday Friday Saturday
5/16 5/17 5/18 5/19 5/20 5/21 5/22

In Excel I have been trying to find an easier way to calculate a time
difference where the times cross midnight. Example:
Start time: 23:50:00
End time: 00:15:00
How would you formulate an equation to determine the duration of time or
differnce between the start and end time?

I have a sheet with a list of names on and I've noticed that when I use ctrl+F to use the find function, even when I know i have entered the correct name it still will not work. I have identifed times when I know the name is there on the sheet, but the find function says "Excel cannot find the data you are searching for"
Im unable to put any pics up as my work pc has java disable so photobucket ect won't work but has anyone else come across this problem and how did you rectify it? A search macro perhaps?

Sorry for the question. Normally I find answers to my excel questions by going through the help tab or by searching on Google. However, I don't even know what question to ask on this one!?!
Basically I have created a spreadsheet with several columns, but I have one column that lists the shirt size (YS, YM, YL, AS, AM, AL, XL, 2X, 3X) of each person. Is there a formula that I can create that will tabulate the number of sizes (i.e. AS=2, AM=7, etc.)?
In previous years I made a column for each size, and simply placed a "1" in the correct column, and had excel just add the 1's from each column. However, that takes more time and space. I was hoping to streamline it this time around.
Thanks for taking the time to read this post. Any help would be appreciated! Thanks, doug

I am trying to figure out how to write a formula to figure out production cycle time.
We will be building 8 "widgets" a day.
We will work 10 hours a day.
There is a 20 minute break at 9:20 am.
Production shuts down for lunch 30 minutes for lunch at 12:30.
Production starts at 6:00 am.
Here is what I can do.
Production cycle time = (10*60)-30/8 or 71.25 minutes
If we start at 6:00 am, the first scheduled cycle completion time = TIME(6,0,0+71.25/1440)
My problem is when I am trying to use a logical "IF' statement to account for the 20 minute break or lunch and still calculate the end of each cycle time through the day I receive a number of error messages.
This is the formula I am trying to make work. I have the cell the formula is in, formatted with a "mm,ss" format.
=(IF(D4+G1/1440>9:20,(D4+G1)/24,(D4+G1+15)/1440))
I have included an attachment to help (a picture is worth a thousand words).
Any help will be greatly appreciated.

i've been trying to figure this out on my own but seem to be hitting road blocks.
i have a column of numbers that we extracted from a database as whole numbers. for instance, 30 should be .30 and 100 should be 1.00. when i try to increase or decrease the decimal point it doesn't allow me to convert it to those positions.
would any one have a tip of how i can easily convert this? there are over 2000 entries in my excel spreadsheet so to do it manually would take a lot of time/effort.
thank you!

Hi all,
I have a dillemma here,
I have to create a schedule which incorporates lunches automatically (either half hour or 1-hour lunches, depending on the circumstances).
The schedule only has time in and time out, but I need excel to automatically deduct the lunch break depending on the circumstance:
If you worked less than 6 hours = no lunch
If you worked more than 6 hours, but less than or equal to 8 hours = 0.5 hour lunch
If you worked more than 8 hours = 1 hour lunch
I am assuming the formula for this will be really long, but I have looked online everywhere and have not found ONE formula for it. I can't put lunch breaks seperately, so all I have to work with is Time in/out.
Also, I wouldn't be able to use military time, so I don't know how excel can assume that time in is in the morning, and time out is in teh evening and/or half-day.
If someone can help it would be greatlyyyy appreciated

I need to have a cell on Sheet2 display the TEXT from a cell on Sheet1, is his possible??
Example:
Sheet1, Cell A1 contains a clients name and I would like to have Sheet2, Sheet3, Sheet4 etc... Display that clients name in a cell of my choosing (could be a different cell on each Sheet) automatically after entering it once on Sheet1, cell A1.
I thought this was possible but I can't seem to figure it out. I haven't done any real Excel work in quite a long time but I thought I had done this before a long time ago!! Any help would be GREATLY appreciated!! Thanks in advance...
P.S. If I use autosum to do this it just displays the number 0, obviously, since it is trying to add numbers...
I uploaded a copy of the spreadsheet, What I would like to happen is have the text from Sheet1,D4 automatically be placed in Sheet2,A1 and Sheet3, B2. Hope this helps
